Abstract
The role of parental occupational exposure in childhood brain tumorswas investigated in a population-based case-control study grouping 251 casesand 601 controls from three European centers: Milan (Italy), Paris (France),and Valencia (Spain). Parental occupational exposure to solvents andpolycyclic aromatic hydrocarbons (PAH) during the five-year period beforebirth was estimated using a job-exposure matrix developed earlier in the samecountries. Odds ratios (OR) of brain tumors for each occupation andoccupational exposure were estimated by logistic regression, adjusting forchild’s age, gender, exposure to tobacco smoke and ionizing radiation,mother’s age and years of schooling, and center. The risk of childhood braintumors rose when fathers worked in agriculture (OR = 2.2, 95 percentconfidence interval [CI] = 1.0-4.7) and motor-vehicle-related occupations. Inthe latter group, the risk increased for primitive neuroectodermal tumors inparticular (OR = 2.7, CI = 1.1-6. 6). Astroglial tumors were more frequentamong children of mothers in health services (OR = 2.2, CI = 1.0-4.9).Paternal exposure to PAHs was associated with an increased, but notdose-related, risk of primitive neuroectodermal tumors (OR = 2.0, CI =1.0-4.0), and maternal exposure to solvents at a high level was associatedwith an increased risk of both astroglial (OR = 2.3, CI = 0.9-5.8) andprimitive neuroectodermal tumors (OR = 3.2, CI = 1.0-10.3).
